Project description:Microbial fermentation is involved in the processing of a dark tea popular for centuries in Northwest China which has shown many health benefits. This study will examine anti-obesity, hyperlipidemic and hyperglycemic effects of CGMCC No.8730 Eurotium cristatum (EC) fermented dark tea (8730DT).

Project description:Lactobacillus paracasei FZU103 on the lipid metabolism in hyperlipidemic mice fed a high-fat diet
Project description:Hyperlipidemia can induce the dysfunction of meibomian gland (MG) in mice, which may be affected by circadian rhythm. However, the underlying mechanism remains unclear. In this study, we exposed the hyperlipidemic mice model induced by three months feeding of high-fat diet to the regular light-dark cycles for two weeks. Then, phenotypic observation and RNA-seq of MG in experimental mice were performed to investigate the effect and transcriptional changes of hyperlipidemia and circadian rhythm on MG dysfunction. As a result, several significantly expressed genes and enriched pathways were identified to be associated with MG dysfunction in hyperlipidemic mice under circadian rhythms. High fat diet can not only bring hyperlipidemia, but also cause meibomian gland dysfunction, which is affected by rhythm genes. These data can provide us with a deeper understanding of the outcomes of MG altered by daily nutritional challenge.
Project description:Dietary proteins have profound effects on lipid metabolism but the mechanism remains to be elucidated. In the present study, we examined the temporal impact of dietary proteins in isoenergetic high fat diets on lipid metabolism of C57BL/6J mice. Mice were first fed a low protein (P) to carbohydrate (C) ratio high-fat diet (L-P/C-HF) for 10 weeks and then a half of mice were changed to a high protein to carbohydrate ratio high-fat diet (H-P/C-HF) for additional 4 weeks whereas the remaining mice continued eating the L-P/C-HF diet.
Project description:Metabolic disorders, such as obesity and type 2 diabetes, are major public health concerns worldwide. Dietary interventions, such as tea consumption, have been suggested as an effective strategy to prevent and treat metabolic disorders. White adipose tissue, as the main energy storage organ in mammals, plays a critical role in the regulation of whole-body metabolism. Recent studies have shown that the microenvironmental cell composition and metabolic network of white adipose tissue can be modulated by dietary factors, including tea consumption. However, the underlying mechanisms and the effects of tea consumption on white adipose tissue in the context of high-fat diet-induced metabolic disorders are not fully understood. Therefore, this study aimed to investigate the effects of tea consumption on the microenvironmental cell composition and metabolic network of white adipose tissue in high-fat diet-fed mice.
Project description:Ramulus Mori (Sangzhi) alkaloids (SZ-A) improves lipid metabolism and adipose tissue inflammation in HFD-induced obese mice.This study compares transcriptome profiling (RNA-seq) in the epididymal adipose tissue of normal chow, high-fat diet (HFD) control and SZ-A-treated HFD mice to verify the regulatory mechanisms of SZ-A. These results demonstrated that SZ-A regulates lipid metabolism and inflammation.
Project description:Analysis of effect of luteolin on lipid metabolism at gene expression level. The hypothesis tested in the present study was that luteolin treatment with obesogenic diet suppressed the hepatic lipogenesis pathways. Conversely, in adipose tissue, luteolin stimulated the lipogenesis pathway and it also simultaneously increased the expression of genes controlling lipolysis and TCA cycle. Results provide important information about the effect on diet-induced obesity and its metabolic complications. Total RNA of liver and adipose tissues was obtained from normal diet, high-fat diet and luteolin added high-fat diet-fed mice and mRNA expression-associated with lipid metabolism was measured.
Project description:Liver X receptor α (LXRα） is a key regulator of lipid homeostasis and effective inhibitors of inflammation. We used the second-generation transcriptome sequencing(RNA-seq) to determine the expression changes of each gene in LXRα-/- mices and wild type mices fed with a chow diet or a high fat diet (HFD).We investigated the downstream molecular mechanisms by which loss of LXRα regulates lipid synthesis and metabolism in HFD.
Project description:In the present study, we designed a 7-week rat model, consuming high-fat diet or heat-misture-treated high fat diet. The liver was used for microarray analyses. Transcriptome profiling reveal that high-fat diet with or with out heat-moisture treatment induced different transcriptome changes, mainly on lipid metabolism and inflammation.
Project description:We report the side-effects of High fat diet on the liver, and foud that the AOS could rescure the side-effect of High fat diet in many factors,such as lipid metabolism and oxidative stress
